Abstract: This paper reviews the state of the art of CAE simulation and analysis methods on disc brake squeal. It covers complex modes analysis, transient analysis, parametrical analysis, and operational simulation. The advantages and limitations of each analysis method are discussed. This review can help analysts to choose right methods and decide new lines of method development. For completeness, analytic methods dealing with continuum models are also briefly covered. This review was made from those papers that the authors are familiar with. It is not meant to be all-inclusive even though the best possible effort has been attempted.

TL;DR: In this paper, the authors present the integration of two different numerical procedures to identify the mechanism bringing to brake instability and to analyse its dynamics, and the two models are compared and the onset of squeal is predicted both in the frequency domain by the linear model and in the time domain by a nonlinear one.

TL;DR: In this article, a detailed three-dimensional finite element model of a real disc brake is developed and three different contact regimes are examined in order to assess the best correlation between the two methodologies.
Abstract: There are typically two different methodologies that can be used to predict squeal in a disc brake, i.e., complex eigenvalue analysis and dynamic transient analysis. The positive real parts of complex eigenvalues indicate the degree of instability of the disc brake and are thought to associate with squeal occurrence or noise intensity. On the other hand, instability in the disc brake can be identified as an initially divergent vibration response using transient analysis. From the literature it appears that the two approaches were performed separately, and their correlation was not much investigated. In addition, there is more than one way of dealing the frictional contact in a disc brake. This paper explores a proper way of conducting both types of analyses and investigates the correlation between them for a large degree-of-freedom disc brake model. A detailed three-dimensional finite element model of a real disc brake is developed. Three different contact regimes are examined in order to assess the best correlation between the two methodologies.

TL;DR: In this paper, the authors investigated the contribution of fundamental frequencies and harmonic components in non-linear transient and stationary dynamics for disc brake system subjected to single and multi-instabilities and showed that an under-estimation of the unstable modes observed in the nonlinear time simulation can be calculated by the stability analysis.

TL;DR: In this article, an experimental tribological analysis performed in parallel to the dynamic one and aimed to highlight the role of the contact problems in the brake squeal phenomena was presented, showing that the surface topography after squeal, by revealing several fatigue evidences, points out the possible increasing of wear rates that are consequent to the squeal vibrations.

TL;DR: In this paper, the authors analyzed the brake squeal data obtained from a full brake system on a noise dynamometer with nonlinear analysis techniques and showed that lower dimensional attractors are isolated and quantified by dynamic invariants such as correlation dimension estimates or Lyapunov exponents.
